CRZ18 (TE85L,Q) application field and working principle

CRZ18 (TE85l,Q) is a series of single zener diodes designed and manufactured by Fairchild Semiconductor.They are ultra-small, ultra-fast and can perform excellent peak power and current handling capabilities.CRZ18 (TE85l,Q) is mainly used to provide voltage regulation, surge protection and other general purpose applications.

The device has a maximum repetitive peak reverse voltage of 18V and a maximum DC forward voltage of 2.4V at 1A forward current.It is made with Silicon epitaxial construction.It has excellent temperature stability and low noise characteristics.It also has a fast recovery time and provides low leakage current.

CRZ18 (TE85l,Q) is designed to provide stable reverse zener operation with excellent temperature stability and superior high frequency performance.The breakdown voltage of the device is designed to maintain tight tolerance, and its excellent avalanche characteristics ensures low zener impedance.The device also has reverse power dissipation capability and is designed to handle high peak pulse currents, which makes it ideal for use in power supply applications.

The working principle behind the CRZ18 (TE85l,Q) series of diodes is quite simple.When reverse voltage is applied, the diode becomes forward biased, allowing electrons to flow through the anode and cathode of the PN junction.This results in a current passing through the device.As the reverse voltage increases, the current through the diode increases.At a certain point, the voltage across the junction reaches its breakdown voltage, and the current suddenly increases, resulting in the diode going into a conducting state.

When the forward voltage across the PN junction exceeds the breakdown voltage, the current passes through the device with much reduced resistance.The peak reverse voltage at which this happens is known as the zener voltage.In the CRZ18 (TE85l,Q), this voltage is 18V.The advantage of this diode is that if the reverse voltage increases beyond the zener voltage, the current through the device remains constant, providing a stable voltage source.

In conclusion, the CRZ18 (TE85l,Q) series of single zener diodes is ideal for applications that require voltage regulation, surge protection, and general purpose use.The device has excellent temperature stability, low leakage current, and reverse power dissipation characteristics.It can handle high peak pulse currents and has a breakdown voltage which is designed to maintain tight tolerances.The working principle behind the device is simple, and the device is designed to maintain constant current when the reverse voltage is increased.
